The Enclosed Arc Lamp

Optical pumping of helium with arc lamp excited LNA lasers

2014 We have developed a compact and relatively inexpensive laser source at 03BB =1.083 03BCm, suitable for optical pumping in helium. The laser is made of an LNA crystal transversely pumped by krypton arc lamps. A cw power of 800 mW has been achieved at 1.083 03BCm with a 3 GHz bandwidth. A 66 % nuclear polarization has been obtained in a 3He gas. Revue Phys. Appl. 24 (1989) 827-831 AOÛT 1989,

High-Power 365 nm UV LED Mercury Arc Lamp Replacement for Photochemistry and Chemical Photolithography

Ultraviolet light emitting diodes (UV LEDs) have become widespread in chemical research as highly efficient light sources for photochemistry and photopolymerization. However, in more complex experimental setups requiring highly concentrated light and highly spatially resolved patterning of the light, high-pressure mercury arc lamps are still widely used because they emit intense UV light from a...

Continuous-wave alexandrite laser pumped by a direct-current mercury arc lamp.

A fluctuation-free mercury arc lamp for the pumping of a cw alexandrite laser is reported. Thermal insulation of a cathode of the lamp permits 4-kW fully vaporized direct-current operation. Fluctuations owing to the pool of liquid mercury in conventional lamp tubes is completely avoided. A 17-W, cw alexandrite laser pumped by the newly developed lamp is described.

Multiple wavelength illumination in flow cytometry using a single arc lamp and a dispersing element.

The principle of a multiple wavelength illumination method for flow cytometers, based upon a combination of a helium-neon laser and an arc lamp as illumination sources is described. By using a prism, the light from the arc lamp is dispersed and the different colors are imaged at different places on the sample stream. The small angle light scattering from the helium-neon laser light is measured ...
